    Robust hand gesture recognition system using motion templates
    (2011) Kulkarni, S.; Manoj, H.; Sumam David, S.; Madumbu, V.; Kumar, Y.S.
    This paper presents a robust hand gesture analysis system. The approach uses the video analytic technique of motion templates rather than conventional gesture recognition algorithms. Also, it utilizes background modeling and skin pixel detection which further strengthens the approach by making it tolerant to background clutter and noise. In addition it reduces the false detections to a considerable extent. The system does not necessitate the user to wear any coloured caps or gloves for the hands. Encouraging results were obtained and it was found that the methodology is flexible and can be manipulated to suit gesture based interaction as per the requirements of a system. It can also be implemented as a standalone system. © 2011 IEEE.

    Design of Mechanically Actuated Aerodynamic Braking System on a Formula Student Race Car
    (Springer India, 2018) Muralidharan, V.; Balakrishnan, A.; Vardhan, V.K.; Meena, N.; Kumar, Y.S.
    Every second in a racing competition counts the performance of a team against the other. Many innovative and sophisticated techniques are being employed to overcome loses in time and add to the performance of the vehicle. Especially in a car racing challenge there is more freedom to install these innovative systems to empower the car to maximum efficiency due to availability of more space. At the global spectrum there are few events which encourage such innovations. Formula Student Racing competitions are one of the global events organized by the Society of Automotive Engineers of different countries which gives opportunity to university students to build and race formula style cars. Like any other racing competitions in this high octane event having an inch over their opponents is always an advantage. Not just better acceleration and high velocities but also good deceleration is required to excel in the competition. Aerodynamic braking system is utilizing the aerodynamic drag force to create high deceleration. This mechanism can be installed on any car with spoilers with minimum modification. Being a student event great amount of care needs to be given to the safety concerns of the driver. © 2017, The Institution of Engineers (India).
